IMPROVEMENT IN GRATES FOR HEATlNG-STOVES.

Specification forming part of Letters Patent No. 59,057, dated October 23, 1866.

To all whom it may concern:

Be it. known that I, GEORGE NIMMo, of J ersey City, in the county of Hudson and State of New Jersey, have invented, made, and applied to use a certain new and useful Improvement in Stoves; and I do hereby declare the following to-be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, wherein- Figure 1 is a vertical section of my improved stove with a single grate. Fig. 2 represents the same improvement as applied with two grates, and Fig. 3 is a longitudinal section at right angles to Fig. 2.

Similar marks of reference denote the same parts.

Stoves have heretofore been made with a hopper or reservoir for coal, and the draft, passing through the fire, has gone off at one side instead ofthrough the mass ofcoal. Thereby the coal only passed down into the fire as the previous coal was consumed.

The nature of my said invention consists in a sliding grate applied below, and combined with a hopper in such a manner that the grate can be drawn away from under the hopper for cleaning out clinkers and ashes. At the same time a plate is drawn below the hopper for preventing the coals falling, and when the kindling materials have been introduced in the grate (if that is required) the grate is pushed back below the hopper, allowing the coal therein to fall down into the grate.

I am enabled by-my construction to combine the hopper for coal with an open grate, so that the fire may be seen, as preferred by many, instead of being closed, as usual in stoves provided with hoppers for coal.

In the drawings, a is the hearth-plate of the stove; b, the grate; c, the coal-hopper, formed between the division d and easing e of the stove. f is the cover of the stove, which, for convenience, is hinged at h, so as to open in the path indicated by the dotted lines, Figs. 1 and 2. g is the pipe or flue for the escape products of combustion.

The grate b is formed of a suitable size and shape, and fitted to slide in suitable ways at 'its ends and i is a plate formed with or attached to the back edge of grate, so that when the grate is slid forward said plate comes below the hopper to sustain the coals in said hopper until the grate has been cleaned of ashes or clinkers and pushed back again to place.

The top of the hopper c is closed by a hinged cover, I, which, when thrown over for introducing coal, covers the flue portion 70 of the stove to prevent coals falling into the same.

When the stove is made double, as seen in Figs. 2 and 3, the covers I, when open, lie at an inclination against the sides of the deflectin g-plate m, that covers the flue 7c and causes the coal to pass into the hoppers c c.' A diagonal plate, it, introduced in the flue It, prevents the products of combustion passing off too suddenly by the flue g.

The products of combustion pass away from the fire at the opening between the division d and the back of the grate.

This stove possesses all the advantages of a radiating-surface and continuity of supply, at the same time that the fire is visible the same as in an open grate.

What 1 claim, and desire to secure by Letters Patent, is-

The sliding grate b and plate z, in combination with the closed hopper c, fitted and operating in the manner and for the purposes set forth.

In witness whereof I have hereunto set my signature this 17th day of July, A. D. 1866.

GEORGE NIMMO.
